I'm going to try to incorporate a wyvern sometime in my current campaign, but I think I have a pretty good idea of how it will happen. A merchant who deals in exotic pets will be involved somehow... perhaps...
- The merchant is looking for someone to capture a live wyvern and tries to hire the party.
- The merchant has already captured a wyvern and wants to sell it to the party.
- A captured wyvern escapes, and the party will need to figure out how to either capture it or get out of its way.
- The party kills a wyvern (maybe just a "random" encounter), and the merchant who wanted to capture it takes revenge on them for spoiling his plans.
Regardless of how they end up in the story, wyverns are interesting (and dangerous) foes worthy of their spot on the tabletop. I should not have neglected them for so long!
This month, as a participant in the A-Z Blog Challenge, I'll be writing a post each day (except for Sundays) and letting the alphabet guide my content. Thematically, all of my April posts (at least those related to the blog challenge) will be monster related. Each day, I'll be challenging myself to create an encounter, NPC, location, etc. that features a monster I've never used before in a roleplaying game. Hopefully this will push me to include more variety in my current campaign, and who knows... maybe I'll find a few new favorites.
